WEIGHING AND BAGGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 647,371, dated April10, 1900. Application filed August 9, 1899. Serial No. 726,657. (Nomodel.)

adjusted as to shut off the supply of grain the moment a certain weightof material is obtained and is indicated by the scale-beam properlybalanced.

Another object of the invention is to mount a grain-receiving hopperupon the scale-beam and provide the hopper with means for holding a bag,and also to provide a support for the bottom of the bag capable ofadjustment to hold bags of different lengths.

The invention consists in the novel construction and combination of theseveral parts,as will be hereinafter fully set forth,and pointed out inthe claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters of reference indicatecorresponding parts in the two figures.

Figure 1 is a side elevation of the improved machine, parts being brokenaway and the chute being shown closed at its delivery end and Fig. 2 isa rear elevation of the machine, parts being broken away and thedelivery end of the chute being shown open.

The scale A is the usual platform-scale and may be of any type. Twouprights 10 are supported on the platform of the scale in any desiredmanner, and these uprights are provided with series of apertures 11 andat their upper ends support a hopper B, the delivery end 12 of thehopper being usually contracted. At said delivery end of the hopper B asleeve or collar 13 is attached, provided with an outwardly-extendingmarginal flange 1-1 at its bottom. and with pins 15, which extend upwardfrom the flange, said pins 15 being adapted to pass through the upperportion of a bag 16, that is to be filled by the material emptied intothe hopper B. The bottom of the bag 16 is supported upon aplatform 17,adjustable upon the standards or uprights 10. At each end of theadjustable platform 17 a pair of braces 18 is located, the upper ends ofeach pair of braces being attached to a sleeve 19, and the said sleevesare mounted to slide on the uprights orstandards 10. Each sleeve isprovided with a horizontal casing 20, and in each casing a.spring-controlled bolt 21 is mounted, adapted to enter the interior of asleeve and in one of the apertures 11 in the standards or uprights 10.Under such construction the platform 17 can be adjusted and held inadjusted position. Asec- 0nd hopper B is mounted upon the upper arm 22of the scale Athrough the medium of a suitable standard 23, and a chuteB is connected at one end with the hopper B, the other end of said chutebeing supported by a brace extending to the upright of the scale A, asshown in Fig. 1. The said chute inclines downwardly from thereceiving-hopper B. This chute is closed at its sides, top, and bottomand is provided near its delivery end with interior vertical sidegrooves 24: and a corresponding slot in the top, the said slot andgrooves being adapted to receive and guide a gate 25, the movement ofwhich gate is effected and regulated through the medium of a screw 26,passed through a lug 27, secured to one side of said gate, the screw 26having bearing at its lower end on a suitable support 28, carried by thechute, as shown in Fig. 1. The object of the gate 25 is to regulate theflow of grain from the receiving-hopper B, as some grain runs much morefreely than others. The gate is therefore raised or lowered according tothe character of grain that is to pass through the chute, providing alarge opening for slowly-moving grain and a smaller opening or space forquickly-moving grain.

The supply of grain is cut off at the delivery end of the chute Bthrough the medium of an end gate 29. This end gate is mounted to slidevertically in the chute and when in its open position is adapted toextend out beyond the top of the chute. Furthermore, the said end gate29, when it is closed, enters a groove in the bottom of the chute, so asto prevent any possible leakage of material The end gate is supported bya lever C, and this lever consists of two angular side sections 31,fulcrumed at the junction of their members on the sides of the chute Bthrough the me dium of suitable pivot-pins 32, and the two side sections31. are connected at the back by a cross-bar 33 and at the front by asecond cross-bar 34, the latter cross-bar being secured to the end gate29 by bolts or rivets 35 or equivalent devices, as shown in Fig. 2. Whenthe end gate 29 is closed, the upper member of each side section of thelever G is horizontal and the other member inclines downwardly, beingparallel with the top and bottom of the chute, as shown in Fig. 1. Anarm 36 is secured to the lower member of a side section 31 of the leverO, which arm extends horizontally beneath the upper member of the sidesection of the lever, as shown in Fig. 1, and a weight 37 is adjustablymounted on the said arm 36. This weight is adapted to regulate therapidity with which the end gate 29 shall fall from its open to itsclosed position. If the weight 37 is brought quite close to the lever,the gate 20 will fall with its full force of gravity and will beretarded in its downward movement proportionately as the weight 37 iscarried toward the out-er end of said arm 36.

A latch-lever D is employed in adjustable connection with theoperating-lever C oi? the end gate. This latch-leverD is of the elbowtype and is fulcrumed upon a suitable standard 38, secured to the upperarm 22 of the scale A, as shown in Fig. 2. The upper end of the lever Dis connected by links 39 with an eye 40 or its equivalent, adj ustablyconnected with the upper member of the weighted side section of theoperating-lever O. The upper movement of the upper member of thelatch-lever D is limited by a stop 41, secured upon the upper portion ofthe standard 38, which upper portion of the standard is inclined, asshown in Fig. 2. The lower member of the latch-lever D is provided witha pivoted finger 42, which is free to move outwardly from the upright ofthe scale, but is prevented from moving toward the said upright. Thislatch-lever D is used in connection with a releasing device E. Thereleasing device E usually consists of a block 43, adjustably attachedto the heel portion of the scale-arm 4A by a screw -15, provided with asuitable nut, as shown in Fig. 1, so that the block 4-3 may be rockedupon its supportingscrew and held in adjusted position, and akeeper-screw L6 is passed upward through the block 43, the upper end ofwhich keeperscrew is beveled at opposite sides.

In operation when the end gate 29 is raised, as shown in Fig. 2, therear portion of the lever 0 is rocked downward, and the finger 42 of thelatch-lever D will pass over the beveled portion of the keeper-screw 4.0and rest against its inner beveled face, as shown in said Fig. 2. Whenthe keeper screw is straight, as shown in Fig, 2, and the scale beam l tis brought to a balance, the linger l2 will slowly pass over the beveledsurface of the keeper-screw t6 and will not have a decided downwardbearing on the said screw, and consequently will not tend to force theheel of the scale-beam downward to any appreciable extent. Since the endgate 20 drops to its closed position as soon as the linger 42 escapesfrom the keeper-screw, it is obvious that when the keeper-screw isstraight but little time will elapse between the actual balance-of thescale-beam and the dropping or closing of the end gate If, however, thekeeper-screw be inclined outwardly, the finger 42 of the latch-lever Dwill more quickly release itself from the keeper-screw, as it will tendto press the heel of the scale-beam downward, an d the end gate willclose very quickly. The adjustment of the releasing device may be madein connection with the adjustment of the weight 87, and such adjustmentsare made to adapt the machine to weighing grain of various kinds. Itwill be understood that the scale-beam L4: is properly balanced when theparts are set up on the scale-platform.

The weight connecting with the gate-lever 0 enables the machine to bereadily adjusted for slight variations of grain in transit. Theprincipal adjustment, however, is made at the releasing device E.

I desire it to be understood that a frictionroller may be placed at theend of the finger 42 of the lock-lever D whenever such addition may befound desirable.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.
